Abstract: A phosphor wheel (13) includes: a first surface having a disk shape; a second surface opposite the first surface; a phosphor layer (13b) having an annular shape and being provided on the first surface; a plurality of openings (13c); and a plurality of first blade parts (33a). The plurality of openings (13c) are disposed radially inward of the annular-shaped phosphor layer (13b) and arrayed along a circumferential direction. The plurality of first blade parts (33a) are located respectively adjacent to the plurality of openings (13c) in the first surface and configured to blow air to a surface of the phosphor layer (13b).

Abstract: Lens barrel includes first group lens frame unit, second group lens frame unit, lens frame, insertion hole, and depressions. First group lens frame unit holds lenses. Second group lens frame unit holds lens. Lens frame is disposed between first group lens frame unit and second group lens frame unit on an inner circumference side of first group lens frame unit through radial clearance. Insertion hole is provided on an outer peripheral surface of first group lens frame unit, and a jig of lens frame is inserted into insertion hole. Depressions are provided at a position accessible from an outside in a state where first group, second group lens frame units and lens frame are assembled, and fix lens frame to first group lens frame unit.

Abstract: Embodiments of a lens barrel may comprise an imaging optical system with a plurality of lenses, a cylindrical focusing manipulation component, a stationary frame, and a restrictor. The focusing manipulation component changes the focal position of the imaging optical system by turning operation around the optical axis of the imaging optical system and to set the distance up to a second imaging region that is at least partially different from a first imaging region, and to move at least some of the lenses of the imaging optical system to switch between first and second imaging states. The restrictor restricts the rotatable range of the focusing manipulation component. When the focusing manipulation component is turned, its rotatable range is switched from a first rotatable range to a second rotatable range.

Abstract: An imaging device comprises an imaging optical system with a plurality of lenses, a focusing manipulation component, an imaging state switching manipulation component, and first, second, third, and fourth restrictors. The focusing manipulation component can be turned to change the focal position formed by the imaging optical system. The imaging state switching manipulation component can be turned to move lenses and switch between the first imaging state and the second imaging state. When the imaging state switching manipulation component is turned, the range over which the focusing manipulation component can be turned is switched from a first range that is restricted by first and second restrictors, to a second range that is restricted by third and fourth restrictors and that is at least partly shifted from the first range.
